I’ve got a new MacBook Pro – one of the Intel i7 ones, 17″, nice piece of kit. I’ve also re-evaluated my external disk requirements on my desktop and bought a dual eSATA/USB RAID0+1 array for storing my Lightroom library.
Sick of running it on USB (and I’m running out of USB ports anyway) I purchased a LaCie SATA II ExpressCard 34 adaptor via Amazon. Today’s been the first chance I’ve had to switch it over as I’m working from home, and installed the drivers as per the instructions. I plugged the card in… instant kernel panic on Snow Leopard. Oops.
No problems, reboot. Except it won’t – not at all. A reboot of the machine hit a kernel panic within a few seconds, not even enough for it to bring up the OS tail. The error is: “thread wants credential but has no BSD process” – a completely unusable system.
I eventually got it down to out-of-date drivers supplied with the CD accompanying the card. The correct drivers are here, and you will not be able to boot your system unless you do the following:
- Reboot holiding down the shift key, so you enter ‘safe boot mode’. This will take a while to boot so you might want to make a cuppa.
- Download the drivers from here.
- Install the drivers and immediately reboot.
I haven’t had any problems since.
(Apparently this is to do with the SIS chipset not addressing 64-bit memory space correctly, but booting into 32-bit compatibility mode doesn’t work either.)
